TYPOGRAPHIC NUMBIEBING MACHINE.

application filed September 23, 1922. Serial No. 590,132.

To all whom 2'25 may concern:

Be it known that we, PETER MALnwie and Josnri-I WALLACE, both citizensof the United States, and residents of the city of Chicago,

6 in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in a TypographicNumbering Machine; and we do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the numerals of reference markedthereon, which form a part of this specification.

This invention relates to improvements in typographic numberingmachines, with special reference to reducing the cost of assembly andrepair thereof by improvements embodied in the main frame and ratchets.

Heretofore, numbering machines intended to be set up with type in formsfor consecutively numbering checks and other work of such a characterhave been constructed with a solid frame that renders such amachine verydifficult to assemble, because of the multiplicity of parts which mustgo together at the same time in definite relationship to each other.

It is an important object of this invention to provide a main frameconstruction permitting a unit or sub-assembly of the many intricateparts entering into theconstruction of a typographic numbering machine.

It is a further important object of this invention to render the severalsub-assemblies mentioned above capable of rapid final assembly by otherthan highly skilled workmen so that users of such devices may themselvesdisassemble the machine for cleaning or repairing with assurance thatthey will be 4 able to put the various parts together correctly. I

It is another object of this invention to retain the ratchets in properspaced relation to the number wheels so that removal of the wheels willnot permit the ratchets to be displaced and consequently be a source ofchilioulty in properly reassembling the wheels in the frame.

Other and further important objects of this invention will be apparentfrom the disclosures in the drawings and the accompanying specification.

The invention (in a preferred form) is illustrated on drawings andhereinafter more fully described. t

On the drawings:

Fig. l is a fragmentary view of a type case containing a typographicnumbering machine embodying the improved features of this invention.

Fig. 2 is an end perspective drawing of the main frame of such anumbering machine.

Fig. 3 is an end view of such a machine with the plunger mechanismomitted.

Fig. 4 is a side elevation of this device with parts omitted.

Fig. 5 is a section on the line 3 with parts omitted.

Fig. 6 is a perspective drawing of a numbering wheel shaft.

As shown on the drawings:

The preferred form of this invention relates to plunger actuatednumbering machines of well known construction, the various parts ofwhich are standard except for the main frame, ratchet spacing and wheelshaft described in detail hereinafter.

The usual construction of such typegraphic consecutive numberingmachines embraces a main fame 1, which will be described more in detailhereinafter, having extending sides 2 with jaws 3 for retaining a casing4; holding a plunger 5 which actuates through a connection 6 a pawlswing 7 and spring pressed pawls 8 which operate to cause consecutiveaction, in a manner well known in the art, of a plurality of numberwheels 9 rotatable on a wheel shaft 10 on the return stroke of theplunger after making an impression. The number wheels are re tained inregister by a plurality of spring finger pressed ratchets 11 with aheavier similar ratchet 12 held into engagement with the index or firstwheel by a torsion spring 13. In the particular form of mechanism 5-5 ofFig.

shown the wheel shaft has an angular de pression milled out along itslength and the intermediate number wheels have movable ciphers which candrop into this depression to prevent printing thereof when nosignificant number is present to the left of said ciphers.

The main frame 1 of this invention comprises a split hingedly connectedcase for the various parts of the machine. The two parts comprising theframe are provided with integrally formed pivots 14 and dowel pins 15are also provided so that the closed frame has the rigidity of a solidframe.

The ratchets 11 and 12 are mounted on a rod 16 inserted through holes 17in one member of the frame, and are retained in correctly spacedrelation to each other by means of bushings or spacers 18 on said rodbetween the ratchets. It has been found that this improvement eliminatesall the previously mentioned difficulty in assembling the number wheelsin the main frame.

The wheel shaft 10 is provided with a square head 19 and a dowel 20seating in suitable apertures 21 in the main frame to bring the angulardepression in the shaft into proper position relative to the printingrside of the frame.

he assembly of a mechanism embodying the improvements which form thesubject matter of this invention is much simpler than with the formerconstruction. The number wheels, pawl swing. and wheel shaft can beassembled with comparatively little trouble when separate from theframe, and the ratchets and bushings can be assembled into the splitmain frame with similar comparative ease. ,Next the wheel and pawlassembly can be placed in the split frame with the dowel 20 registeringwith its aperture in the frame when the frame may be clos'ed, and theconnection 6 and plunger andcasing added and held in place in the jawsprovided therefor on the main frame.

We claim as our invention:

1. In a numbering machine, a set of printing number wheels, mechanismfor actuating said wheels to bring the numerals in proper order intoposition at the printing face of the device and a frame for housing andsupporting said mechanism, said frame including two pairs of endmembers, one pair at each end of the frame, the members of each pairbeing pivoted together cent the printing face of the device.

2. In a numbering machine, a set of print-- ing. number wheels,mechanism for actuating said wheels to bring the numerals in properorder into position at the printing face of the device and a frame forhousing and supporting said mechanism, said frame including two pairs ofend members, one

pair at each end of the frame, the members of each pair being pivotedtogether adjacent the printing face of the device, said frame connectingthe end members at only the corners opposite said printing face.

3. In a numbering machine, a set of print ing number wheels, mechanismfor actuating said wheels to bring the numerals in proper order intoposition at the printing face of the device, a plunger for operatingsaid mechanism, a frame for housing and supporting said mechanism, saidframe including two pairs of end members, one pair at each end of theframe, the members of each pair being pivoted together adjacent theprinting face of the device, flanges one on each of one pair of said endmembers, a casing for said plunger and means for securing said casingbetween said flanges.

4. In a numbering machine, a set of printing number wheels, mechanismfor actuating said wheels to bring the numerals in proper order intoposition at the printing face of the device, a frame for housing andsupporting said mechanism, said frame including two pairs of endmembers, one pair at each end of the frame, the members of each pairbeing pivoted together adjacent the. printing face of the device and adowel pin on one member of each pair the other member of each pairhaving a cooperating dowel hole, said pins and holes being adjacent theside of the device opposite the printing face.
